Demolishing a building may require planning permission or prior approval, depending on factors such as the building’s type, size, and location.
Before starting any demolition work, it’s important to consult your local planning authority to confirm what permissions are needed. This helps avoid the risk of enforcement action or legal consequences.
You will also need to ensure you conform to the building regulations around the demolishing of a building.
You likely will require advertisement consent to display a commercial advertisement outside your home, especially when the company does not operate from that location.
It is more likely that permission will be required where:
- the sign is over 0.3 square metres or illuminated
- the sign is visible from a road
- the building is listed or in a designated area then consent

Verandas will often require planning permission as they do not fall under permitted development rights. If the veranda is raised over 0.3 metres, covers more than 50% of the land around your house, is on the principal elevation or on a roof then it will need planning permission.
You may require additional consents if you live in a Conservation Area or listed building. If you are unsure, you should contact your local planning authority.
For more information about planning permission for verandas and balconies, read our common project.
It is likely that you will require planning permission to extend an existing front porch to add a toilet.
Adding a porch falls within permitted development rights meaning an application for planning permission is not required provided specified limits and conditions are met. However, to fall under permitted development rights for a porch, the total ground area must not exceed three square metres. This is unlikely to be enough room to fit toilet and the required additional components.
Read the full rules for porches under permitted development on our mini guides.
If your porch exceeds these limits, it will be classified as an extension. These can be permitted development but come with a different set of rules.
Extensions are not permitted development if they are built forward of the ‘principal elevation’ of the house. As such, you will be required to submit an application for planning permission to your local planning authority.
If you live in a listed building, you will need listed building consent for any significant changes.
In many cases, you can extend a house without applying for planning permission by using what's known as permitted development rights, provided certain limits and conditions are met. However, if your plans go beyond these restrictions, you will likely need to apply for householder planning permission.
You do not need planning permission to move internal walls.
Removing a load bearing wall will require building control approval as it is altering the structure of the property. You will be required to provide a report from a structural engineer who will provide structural calculations.
Work on internal walls may also affect fire escape routes, ventilation, drainage or electrics. These should be considered during the design process and work should be carried out by a member of the competent person scheme where possible.
In most cases, yes - planning permission is required to operate a business from your garage. This is because the use would no longer be purely domestic, and the garage would be considered to have changed use from residential (Class C3) to a business-related use, which requires planning consent.
A bin store is classed as an outbuilding, these fall under permitted development rules meaning they are allowed as long as they adhere to a set list of rules. However, one of these rules is that outbuildings cannot be placed in front of the principal elevation*. As such, you will be required to apply for planning permission to build a bin store or any permanent structure in your front garden.
Read more about the rules for outbuildings.
Principle elevation - The most visible or prominent side of a structure, typically facing a street or public area. While often considered the 'front' of the building, it may not always contain the main entrance.
Adding a new driveway to an unclassified road for access to a house or business falls under permitted development rights, meaning no application for planning permission is required.
If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.
You will have to apply to the relevant highway authority for a dropped kerb if you wish to cross a pavement to access your property.
You will not need to apply for planning permission if you wish to erect a new; or alter, maintain, improve or take down* an existing fence, wall or gate if certain conditions are met. If any of the conditions are not met, then you will need to apply for planning permission.
Find out about the limits and conditions for fences, gates and walls.
Fences, walls and gates do not require building regulation approval. Even though building regulations do not apply, the structures must be structurally sound and maintained.
If you share a wall with a neighbour, it may be classed as a ‘party fence wall’.
Common Questions
Two storey rear extensions are considered to be permitted development, meaning they do not require an application for planning permission provided certain limits and conditions are met. If these limits are exceeded then you will need to apply for planning permission from the local planning authority.
Houses on designated land such as national parks or conservation areas are excluded from the permitted development rights and will require an application for planning permission.
To fall within permitted development rights, the extension should be no higher than the existing house, and where it is within two metres of a boundary, the eaves should be no higher than three metres.
Any double storey extension to the side or front of the house will require planning permission. You can view the full limits and conditions on our Two-storey extension Mini Guide.
If you live in a listed building you will require listed building consent for any major works to the property.
In many cases, yes. Converting a single residential property (Class C3) into a small House in Multiple Occupation (HMO) for up to six occupants can often be done under permitted development rights, specifically under Class L. This means that planning permission isn’t usually required.
However, if your property is located in an area covered by an Article 4 Direction, permitted development rights are removed, and you would need to apply for full planning permission to change the use from C3 (dwellinghouse) to C4 (HMO).

Yes, but this type of conversion will require full planning permission. This is because you’d be changing the use of the ground floor from residential to commercial (typically to a use class such as E), while the upper floor would remain as a residential flat (Class C3). The change of use triggers the need for planning approval.
Find out more about change of use
Yes, but you will need to obtain planning permission. Converting a detached garage into a self-contained living space, such as annexe, studio flat, or retail unit, represents a material change of use, particularly if it will function independently from the main house. This is because the garage would no longer be used in connection with the main dwelling and would effectively become a separate residential unit.
You may wish to make loft alterations to enhance the storage facilities available or to increase the living space of the home. Converting the loft of a house is considered to be permitted development (not requiring an application for planning permission) subject to certain limits and conditions.
Remember, building regulations approval is required to convert a loft or attic into a liveable space.

There are different rules for flats and maisonettes regarding loft conversions. Read guidance for converting the loft of a top floor flat.
